It features a triangular insert shape with a 60-degree included angle, a 1\/4 inch inscribed circle, and a 1\/64 inch corner radius for sharp, consistent edge geometry. The insert uses a positive rake angle and F1 chip breaker configuration, making it well suited for finishing and light-to-medium material removal on difficult-to-machine metals. It is installed via screw holding method and provides three usable cutting edges per insert.\u003c\/p\u003e\u003cp\u003eThis insert is primarily intended for machining superalloys and titanium, with secondary suitability for steel, cast iron, non-ferrous metals, and hardened materials as indicated by secondary workpiece material codes M, K, N, and H. Typical applications include turning, facing, boring, and back turning operations in aerospace, energy, and high-performance manufacturing environments. The F1 chip breaker geometry supports controlled chip evacuation in tight-tolerance setups. Material grades S10, S20, and S25 indicate the grade range for this uncoated carbide substrate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with bright uncoated finish for maximum edge sharpness on superalloys and titanium\u003c\/li\u003e\n\u003cli\u003eF1 chip breaker geometry supports chip control in turning, facing, boring, and back turning\u003c\/li\u003e\n\u003cli\u003eThree cutting edges per triangular insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003ePositive rake and sharp cutting edge style reduce cutting forces on difficult materials\u003c\/li\u003e\n\u003cli\u003eScrew-mount holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ISO code TCMT110204-F1, industry standard number TCMT21.51-F1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TCMT-style screw-on insert toolholders accepting a 1\/4 inch inscribed circle triangular insert.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer when securing the insert to avoid cracking the carbide substrate.
